"A LEGO Brickumentary" is exactly what the title suggests, a documentary about the LEGO company and the little brick building toys that have been in the world since the late 1950s. According to the documentary, LEGO is the second-biggest toy company in the world, and considering that it pretty much makes only one type of product, that's remarkable. The film has the built-in interest of anything that explains the origins of a ubiquitous and seemingly eternal product.
